Cygwin compile work

[joevenzon]

Sorry about breaking the builds

No worries.

Is it possible that the build on other platforms broke because env['IS_WIN'] was only intialized on windows builds?

Yep, that's what the error message was about.

perhaps adding env['IS_WIN'] = False on the other platform intialization fixes will also fix things.

It probably would have. I actually tried to fix it another way; replace all of the

Code:

if env['IS_WIN']:

with

Code:

if ( 'win32' == sys.platform or 'cygwin' == sys.platform ):

I tested this fix on my mingw/msys setup on windows and it compiles fine with the changes. Can you see if R1891 works for you?
